A dentary fragment of a great evening bat Ia io Thomas, 1902 found in 2020 in the Pleistocene deposits of the Lang Trang karstic cave in northern Vietnam is described. This rare species of large tropical bats now inhabits Nepal, eastern India, southern China, Thailand, Laos, and Vietnam and as a fossil is known from the Pleistocene of China. In Vietnam the fossil remains of this species have been discovered for the first time. By the total size and lower molar structure, the specimen from the Lang Trang cave is most similar to the subspecies Ia io peninsulata Soisook et al., 2017 that now occurs in southern Thailand.
描述了 2020 年在越南北部朗特朗喀斯特洞穴的更新世沉积物中发现的一种大型夜蝠 Ia io Thomas, 1902 的齿骨碎片。这种稀有的大型热带蝙蝠现在分布在尼泊尔、印度东部、中国南部、泰国、老挝和越南，作为化石，在中国更新世也有发现。这是该物种在越南的首次化石发现。根据总体大小和下臼齿结构，朗特朗洞穴的标本与现在分布在泰国南部的亚种 Ia io peninsulata Soisook et al., 2017 最为相似。
